I wanted to try this cheap fucking tester on offer on Aliexpress.

I don’t have much to say, it works quite well, i tried to make some measurements of a couple of electrolytic capacitors and making the comparison between LCR-T7 and the PEAK ATLAS ESR+ (paid almost 15 times more) the measurement result it’s almost identical.

Surely the positive side of this small and fragile object that will surely stop to working one day to another :-D which allows you to measure/test a fairly vast category of components.

Example:

• Diodes
• Zener diodes
• Resistors
• Potentiometers
• Electrolytic/Tantalum Capacitors
• Ceramic/Polyester capacitors
• Inductors
• SCR
• Triacs
• Transistors (N-E-MOS,P-E-MOS,N-MOS,P-MOS,N-JFET,P-JFET,N-IGBT,P-IGBT)
• Transistors PNP,NPN
• Battery (max 4.5v)

It also has an infrared remote control decoder which i find absolutely useless.

The microcontroller used in the LCR-T7 is a clone of the ATMEL ATMEGA328, the Lucky Green LGT8F328P which is practically identical to the ATMEL but with additional capabilities such as higher speed and has a higher resolution for converting analog signals and having a digital-to-analog converter as well.

Below are the photos of the inside.

What is DiagROM?

DiagROM is a diagnostic tool for the amiga computers.

And it is to be used on defective machines, trying to help no-boot situations etc.

You simply replace the Kickstart roms in the Amiga with the DiagROM. and when poweron. your Amiga will start a diagnostic software. It will try to dump info on the serialport (and actual menus etc aswell) while also trying on the screen.

Changelog:

• Well decided to release 1.3 far too many people are still using 1.2.1 so this is now the releaseversion.
• Read the text “FuturePlans.txt” for more info.
• three might be updates. as V1.3 please check the date. but it will be bugfixes only.
• Now default also produces a CD32 image to be burned on 27C800 Proms.
• Fixed issue with ghostfastmem found on AA3000+ boards (detectes fastmem that isn’t there)
• Fixed Addresserrorissue while playing testmodule on 68000 machines.
• Fixed issue with Autoconfig printing forever (actually 65535 times) if there was no cards detected.
• On RGB test. added white bars at every colorchange to make it more easy to count out what color is shown.
• RTC test: added a adjustfunction telling how many frames between everytime RTC changes (second) to help adjusting RTC.
• Added function to constantly monitor one memaddress. This is for dev of new hardware and not to diagnose issues.
• Fixed addresserror crash on audiotest using 68000/010 CPU
• Changed memorytestroutines to the new updated.
• Fixed autoconfig so it would not end in a endless loop if no autoconfigcards was detected.
• Fixed autoconfig with outside checking from github to handle boards with an illegal configuration better.
• Simple Audio waveformtest now supports volumechanges and also HOPEFULLY oddbyte-bug in Sinuswaves are fixed
• Some minor undocumented bugfixes.
• Now the new memtestroutine actually seems to work “x” is just hardcoded testareas, but the manual option “7” now lets you
• select what area to test and the depth of check (how many longwords between all tests 1 being every byte checked) (higher=faster test)
• AGAIN Long pause.. ERASED the memtestroutine I was working on redid it TOTALLY!. available as “x” in memtest menu!
• New Memtestroutine now should handle when colliding with workareas.
• Manualtest routine now swapped to the new testroutine. you can now enter selected area to scan AND change blocksize.
• higher blocksize=more accurate addresstest check.
• also if you enter wrong order of area to scan it will be handled. 0 byte scanarea will cancel.
• New experimental memtestroutine in the works. right now only doing a test of HARDCODED 16MB fastmem on A4k/3k
• Should be much faster, ASWELL as it should handle address-error issues! TEST IT HARD PLEASE!
• Also contains bug in Zorro handling asking boards to be shut down, issued via Github! (thanx!!)
• Noticed that CSPPC did not work on DiagROM. This as it seems the board needs time to startup (HEY P5.. handle it with RST??)
• so doing some waiting and resetmagic if a CSPPC is detected. not it starts OFTEN! (not always, if not. do a reset and it will start)
• Fixed bug so if no chipmem available at boot, it doesnt try to do a addresserrortest of that area anyway.
• Fixed scrollbug leaving traces of lowest pixelrow.
• Added function in Autoconfig mode that lists a summary of detected boards.
• Added About text.
• Added support for handling 2 different workmem areas: Chipmem and Fastmem, showing info about it in systeminfo screen.
• Systeminfo screen if detecting a 060 will show PCR registerbits.
• If A3000/A4000 motherboard memory or CPU slot memory is found scanning of A1200 CPU Slot memory is disabled, This will hopefully stop
• machine to crash with a 3640 installed and maprom enabled.
• Found a interesting behaviour on Amiga 4000. If you have no chipmem, and write something to any chipmemaddress and then
• read anything from any chipmemadress (not even same as you wrote to) THAT value will be read! so on an A4000 with no chip.
• the memorydetectroutine would say that it finds a shadowram. also the UDS/LDS test said “ok” even it it impossible could be.
• so fixed that by doing a write to chipmem with $ffffffff so it will read that if you do not have any chipmem. making the tests more true.
• A1k Version have not been working for a while due to spaceissues. removed more or less all “not important” tests tomake it fit into the
• very limited 64k bootrom. so it should work again.
• Fixed bugs when using a 68000 CPU (010 aswell?) that crashed IRQ/CIA tests and also Extended chipmemtest. (Addresserror etc)
• Also fixed more information in crashscreen.
• During Startup, UDS/LDS test was done by writing $ff to diferent places, this could be wrong as no memory can also
• show up as $ff changed value to $aa to be more “random” if memory is not present.
• At startup, chipmem is filled with its memoryaddress, while doing this you see a checkered-pattern on screen.
• After that, it verifies that the address contains that data, while doing this you see a distorded colorpattern on screen.
• if fail, it will show what memaddress it fails at, memaddress as binary and also what it actually contained (should be its same address)
• So no more telling ram is ok when thee was shorted/missing addresslines. Now check actually checks ALL memory and not only beginning.
• Doing Addresserrorchecks on Chipmem AND workarea.. if left mousebutton pressed at poweron.
• fastmem is chosen ar priority ram, if no fastmem found, chipmem will be used but screen turned off.
• if addresserror found in chipmem, chipmem will be discarded. will be handled different later
• New initcode in start. at memfail bits read will be written as green is correct, red if failed.
• Also during error, a dividertext will be printed every 512k block

Ikari has released a new firmware for the SD2Snes / FXPAK Pro Flash Cartridge (Super Nintendo/Famicom). The upgrade instructions can be found here.

Sorry for the delay, but it just escaped me to post it here.

Features added:

• First firmware release to support FXPAK Pro Rev. D
• [All] USB (usb2snes) support by RedGuy.
• [All] save state support (via USB/savestate2snes) by acmlm, total, Myria, RedGuy, FURiOUS, ikari_01
• [All] stand-alone save state features by FURiOUS
• [All] some compatibility improvements and optimizations for stand-alone save states by ikari_01
  • Add support for YAML list items for multiple savestate_fixes entries per game
  • Add support for simple bitwise operations on savestate_fixes patches
  • Add support for verbatim code execution on savestate_fixes patches – notably fixes Star Ocean (decompressed) save states (however the save state hook still needs CPU time optimization to prevent music glitches in Star Ocean.)
  • Add IRQ support on top of NMI for the save state hook – this enables save states on Out Of This World and possibly other games that only use IRQ. Also fixes controller input capture on a number of games so the game-specific input hacks could be eliminated.
  • Moved save state code outside of the USB hook area to make room for USB hook execution.
• [All] SGB support by Redacted173.
• [All] favorite games list by freelancer42

Fixes:

• [All] Fixed savestates crashing occasionally when loading (and sometimes saving)
• [All] Fixed Star Fox locking up during sortie sequence when in-game hooks are enabled.
• [All] Updated FURiOUS’s Savestates Readme to reflect changes pertaining to In-game hook.
• [All] Fixed data caching bug in MSU1 data extension which could cause wrong data to be streamed.
• [All] Savestates: do not try to capture data that is already in cartridge space anyway (e.g. SRAM). Fixes text distortion in Near’s Bahamut Lagoon translation when loading a state.
• [All] Fixed YAML config parser to support comment signs after list start items
• [All] Fixed SNES open-bus contamination (fixes sprite flickering in Near’s Bahamut Lagoon translation, certain speed runs that rely on open bus behaviour)
• [All] (hopefully) fixed rapid data line toggling sometimes resulting in address line glitches, causing random crashes in extreme cases, and occasional garbled graphics on SMRPG among others.
• [All] Fixed data integrity problems when loading BSX games.

Known issues:

• Due to integration of the savestate handler into the in-game hook, the SNES CPU cycle cost for the in-game hook has increased. This reintroduces some issues when in-game hook+savestates are enabled, such as a corrupted Equip menu in Final Fantasy III/VI. I am planning to do an overhaul of the savestate code which will address this issue as well.
• When in-game savestates are enabled and set to the default button combination, pushing the buttons to temporarily or permanently disable the in-game hook will result in a crash. This happens due to overlap with the savestate button combination.
• When in-game savestates are enabled and the “load state” button combination is pressed, the handler will try to load a state even if no state exists yet for the current game. This will lead to a crash and sometimes results in a still image being displayed from a previously played game’s savestate.

WOW This is a long time since I updated this. And lets be honest. I have forgot what i have changed.
BUT one thing I just been thinking. I have bumped the versionnumber in the wrong “end”.. so as I am working on a new init-routine. I consider this is the “stable” one.
So I bump the serialnumber to 1.2.1. I have been too busy with hardware so I must confess I haven’t coded so much on DiagROM. I have made some minor bugfixes etc.
I must still warn that if a routine is experimental you cannot really trust the tests.
Anyway in hope for the best in the future. the “daily” will for a while be a little “jumpy” while I get the new init working. This should be useful meanwhile.

Changelog:

• Now Diskdrivetest should work on most machines.
• Memchecks should now detect non working ram better.
• Experimental CIA test added that should work on NTSC machines aswell. MIGHT give false results on TOD-B  tests. It will still say that IRQ is needed, this is not true :)
• Added RGB Test.
• Usual “bugfixes” pressing left mousebutton when chipmemdetect starts skips serial output and makes startup faster. holding down left mousebutton while doing memscan at start skips memtests. (good if it hangs during scan. known not found bug yet!)
• Updated to tested values if new CIA test that should be more correct.
• Also in memoryedit mode (memtest) added pageup/down functions with Q and Z keys.
• (or Amigastandard shift+cursor keys)  also added official support to execute code from current locaton using the X key. (this is very much not really useful for most people)

Changelog:

• Revert S-DD1 bitfile to earlier build which happens to less expose a timing hazard. This will need further examination for a proper fix. Fixes severe glitches with S-DD1
• Fix swapped logic terms in SA-1 and SuperFX RAM write cycles. Fixes severe glitches on SA-1 and SuperFX on Mk.II units; The bug was also present in the Pro firmware but didn’t seem to have much of an effect
• Fix game video mode setting in SuperCIC pair mode.

Ikari has released a new firmware for the SD2Snes Flash Cartridge (Super Nintendo/Famicom). The upgrade instructions can be found here.

Cumulative Changelog:

• S-DD1 support by Magno! Big thanks to Magno who implemented it and RedGuy who helped integrate the core with the main firmware :)
• Support for sd2snes Mk.III (a.k.a. SD2SNES Pro). This works by adding a new set of support files for the new hardware so the firmware package actually contains two firmwares. This also makes it possible to swap the same card between old and new sd2sneses freely.
• Fixes:
  • Fix memory corruption on BS-X loading. (Hopefully – I could not identify a cause and suspect bitstream file corruption. Please let me know if it works again – it does for me)
  • S-RTC register state is REALLY reset when the console is reset, and also when loading a game.
  • Actually boot on SD2SNES Pro.
• Known issues:
  • Firmware seems to ignore Cx4 speed setting (at least since v1.9.0)
  • sd2snes Pro menu still has the old design
  • Mk.III specific source code changes currently aren’t contained in the GitHub repository. Please bear with me while I figure out a way to integrate them. ;)

Ikari has released a new firmware for the SD2Snes Flash Cartridge (Super Nintendo/Famicom). The upgrade instructions can be found here.

Changelog:

• SA-1 support by RedGuy! Big thanks to RedGuy again :) This was a really tight fit for the FPGA so there’s a little catch – MSU1 is not available for SA-1 games.
• Also from RedGuy comes partial SRAM detection for some known games (SuperFX & SA-1). This calculates a ROM CRC and chooses to monitor only specific regions in cartridge RAM for changes. This enables automatic saving without having to resort to periodic saving, reducing wear on the SD card.
• SNES CPU <-> PPU clock phase alignment. This is a long standing issue on a sub-CPU-cycle base inside the SNES. HDMA to certain registers can cause flickering sprite slabs to appear when CPU and PPU are out of phase after a cart-side reset (which does not reset the PPUs). This fixes the notorious flickering of characters with the giant frog attack in Chrono Trigger, sprites in Kirby Super Star, characters behind the text box in Star Ocean, and probably more. See https://github.com/RedGuyyyy/sd2snes/issues/6 for technical details.
• Added an option to always go back to menu on reset, regardless of whether it’s a short or long reset.
• LED brightness setting (16 levels)
• Added an option to choose whether you want to start a game with or without cheats enabled (of those that are marked as enabled in the YAML file). You can enable / disable them later using the L+R+Start+A / L+R+Start+B button combinations if you have in-game buttons enabled.
• Disable Satellaview emulation when a real Satellaview base unit is detected to avoid bus fighting and facilitate Satellaview development.
• System Information now shows the currently effective video mode (50 or 60 Hz).
• Fixes:
  • Control signal edges are detected a bit earlier, improving stability on some consoles (Github Issues)
  • Fix timing of auto region patching. This should solve cross-issues with Super Scope games because they rely on the same register that is also used to read the console region.
  • Fix brightness patching / limiting for games that use HDMA to alter the brightness register. (e.g. Star Fox)
  • Fix an occasional imaginary access cycle carried out by the FPGA after reconfiguration. This fixes lockups when loading games with dedicated FPGA files, i.e. SuperFX, SA-1, OBC-1.
  • Fix SuperCIC pair mode entry for consoles with ≤ 3.072MHz CIC clock (notably GPM revisions). (Github Issue)
  • S-RTC register state is reset when the console is reset.

• A600/1200/4000 IDE detection.
• Some bugfixes. (look at releasedata for more info)
• Powerup extras:
  • press left mousebutton at power on, Screen will be disabled and IF there is fastmem present, fastmem will be used instead of chipmem.  Serial console is only option.
  • if you press right mousebutton at poweron. Computer will use the beginning of detected ramblock instead of end.
  • (you can combine both buttons at boot)
• fire on joystick at power on:
  • Serialport output is disabled. this to make the machine to start with broken Paula.  DiagROM also tries to detect broken paula at start and will disable serial if detected. (this detection is far from 100%)

SNK Neo Geo Mini (40th Anniversary) JAP Version.

The Neo Geo Mini is an all-in-one system designed like a mini arcade cabinet with 40 classic games on board.

The 3.5-inch 4:3 screen isn’t going to deliver amazing viewing angles or contrast, but it looks fine head-on and, critically, it displays everything in a crisp, native resolution, which is essential for the art of these games.

There’s a pleasingly substantial power button on the back as well as three USB-C ports — two for controllers, one for power. The back panel also houses a Mini HDMI port and a headphone jack.

The selection of games is not going to be for everyone, but then neither is SNK’s history in general.

Twenty-five of the 40 games are 2D fighters, including all 10 King of Fighters titles that ran on Neo Geo arcade hardware, three Samurai Shodown games, the first Art of Fighting, and four Fatal Fury games, including the eternal classic Garou: Mark of the Wolves.

Elsewhere, you’ll find side-scrolling shooters like Metal Slug 1 through 3, along with shmups like Blazing Star and Twinkle Star Sprites.

I took unpretentious photos, if you are interested in photos with a excellent quality of the neogeo mini just search on the net, also you can see i have not yet attached the stickers that are supplied as standard.

Now you can also insult me because I bought an object like that, saying the usual and banal phrase: but it’s a raspberry! you know that i couldn’t care less.

Very nice adapter designed by Rolo that allows you to use the Rolo Multi-Cartridge also on the Emerson Arcadia 2001 / GIG Leonardo and Hanimex HMG-2650 console.

The Eprom need to be installed in the Multi-Cartridge and contains 64 games all fully working.

This is a good alternative for those who don’t want to spend an important amount of money for the Multicart Arcadia 2001.

Thanks Rolo for this great extension (Adapter) for the Multi-Cartridge.

Ikari has released a new firmware for the SD2Snes Flash Cartridge (Super Nintendo/Famicom). The upgrade instructions can be found here.

Changelog:

• SuperFX support by RedGuy! This is the duck’s guts. What an accomplishment. Big thanks to RedGuy!
• EXPERIMENTAL brightness patching for S-CPUN based consoles (1CHIP/Jr). The patching is comprised of two parts:
  • 1CHIP transient fix – tries to alleviate some graphical issues with 1CHIP consoles where it reacts unfavorably to sudden changes to the brightness register. This fixes the shadow in Air Strike Patrol, warped scanlines in Rudra’s Treasure, and faded scanlines at the top of the screen on certain Capcom games when the console is equipped with a de-ghosting fix involving the replacement of the C11 capacitor.
  • Brightness limit – can be used to limit brightness on consoles where the stock RGB levels are too high.

• NOTE: There are known problems with games that use DMA to set the brightness register. Notably Star Fox and some MSU1 video players. You should disable it if you intend to play those. For now I’m releasing it as is because I still think it can be useful (and I’ll be gone for two weeks and didn’t want to delay this release any further :-D)
• Added ExLoROM support (LoROM > 32Mbits)
• The In-game hook is now disabled by default.
• Touched up the menu a bit – dependent settings are printed in grey if the higher-level setting is disabled
• Changed the version numbering by eliminating the eternal leading zero. The last digit can now be used for small revisions or fixes.

Some minor fixes are still outstanding which I will address in a couple of weeks after I have returned from vacation.
